STEAM ENGINE LUBRICATING ATTACHMENT.

SPECIFICATION forming part of Letters Patent No. 271,005, dated January23, 1883.

application filed December 11, 1882. (No model.)

To all whom 'it may concer/n Be it known that I, H. HERMAN WESTLNG-HOUSE, of Pittsburg, county ofAlleghen y, State of Pennsylvania, haveinvented or discovered a new and useful Improvement in Steam-EngineLubricating Attachments; and I do hereby declare the following to be afull, clear, concise, and exact description thereof, reference being hadto the accompanying drawing, making part ot' this speciication.

The figure represents a vertical sectional view of an uprightdoublecylinder single-aoting steam-engine* operating by a directconnection, and with the features of improvement hereinafter describedand claimed applied thereto. j

The steam-engine shown in the drawing has substantially the constructionand operation shown and described in Patent No. 240,482, granted to' meApril 19, 1881; but I have shown it only as one form of engine to whichmy present improvements may be applied.

A represents one of the steam-cylinders, and V the valve-chamber. Directconnection is made bypitman R and connecting-rod V5 with the propercranks or eccentrics on the main shaft YV. A close oil-tank is alsoprovided, and the shaft YV passes through the same in such manner thatat each downstroke of pistons and valve the cranks or eccentrics willdash violently` into the oil or other lubricant in the tank, and by apump, as in said patent or in Patent No. 246,258, or by a spraying orspattering action, will effect the proper lubrication of the movingparts.

Now, I have found in the use of engines o this class that steam willsometimes leak into the vat Y, or in consequence of the heat the oil orother lubricant in the vat will give off vapors in small amount, andthat these should have a vent, and obviously any vent that may,

be provided should be such that oil-cannot by spraying or spatterin gpermanently escape thereat; and I have also found that the steam whichso leaks into the vat will sometimes a vent-pipe, a, at any desiredpoint above the level of the oil, and preferably at a-co1isidera bledistance above, and carry such vent-pipe aout to' such distance orinsuch direction that any drops of oil that may be spattered into it willdrop or come practically to rest. 'lhe outer end of such pipe opens intoa pipe or funnel, o, open at its upper end,so that steam and vapor mayescape freely, and also into a 'return drip-pipe, c', which latter leadsback into the vat. Then the'oil which may enter the vent-pipe a will runinto the pipe c and back into the vat; and this pipe o' gives aconvenient meansof attaching a glass gage, d, by which to note thcheight of the oil in the tank or vat Y. i

In cases where trouble is experienced or is liable to arise from thepresence ot' water of condensation in the vat in excessive amount, I adda pipe, e, which enters the vat at a point below the lowest level orbottom of the oil' stratum, and extends upward to the height of thesurface ofthe oil, or to the height at which itisdesired the oil shouldbe maintained. The pipe e may here have a free disch-arge or extend oft'to any point or placeot' waste. 'lhen water ofcondensation, as itaccumulates in the vat, will settle at the bottom, and as it becomesexcessive in amount will flow ot' freely by the pipe e. It will beunderstood that the presence -of a moderate amount of Water in thebottom ot' the vat beneath the oil is no objection, and on some accountsis an advantage.

The device thus described may be used advantageously as an attachment toany form or styleof engine havin g a close or comparatively closeoil-vat, wherein lubrication of some or all of the moving parts iseffected by the spraying or spattering of the lubricant effected by themovements of the crank-shaft.

The feature ot' a vent and drip pipe may be embodied in a somewhatmodified form byextending the pipe a with an upward bend, as

represented by dotted outline at a; butin suchv 'water in condensed formshall be prevented,

and whatever may get into such pipe will be carried back into the vat.
